SYNOPSIS

package main;

use Data::Object;

my $array = Array [1..4];

# my $iterator = $array->iterator;

# $iterator->next; # 1

DESCRIPTION

This package automatically exports and provides constructor functions for creating chainable data type objects from raw Perl data types.

LIBRARIES

This package uses type constraints from:

Data::Object::Types

FUNCTIONS

This package implements the following functions:

array

Array(ArrayRef $data) : InstanceOf["Data::Object::Box"]

The Array function returns a Data::Object::Box which wraps a Data::Object::Array object.

my $array = Array; # []

Array example #2

package main;

my $array = Array [1..4];

boolean

Boolean(Bool $data) : BooleanObject

The Boolean function returns a Data::Object::Boolean object representing a true or false value.

Boolean example #1

package main;

my $boolean = Boolean;

Boolean example #2

package main;

my $boolean = Boolean 0;

box

Box(Any $data) : InstanceOf["Data::Object::Box"]

The Box function returns a Data::Object::Box object representing a data type object which is automatically deduced.

Box example #1

Code example #1

package main;

my $code = Code;

Code example #2

package main;

my $code = Code sub { shift };

false

False() : BooleanObject

The False function returns a Data::Object::Boolean object representing a false value.

False example #1

package main;

my $false = False;

float

Float(Num $data) : InstanceOf["Data::Object::Box"]

The Float function returns a Data::Object::Box which wraps a Data::Object::Float object.

Float example #1

package main;

my $float = Float;

Float example #2

package main;

my $float = Float '0.0';

hash

Hash(HashRef $data) : InstanceOf["Data::Object::Box"]

The Hash function returns a Data::Object::Box which wraps a Data::Object::Hash object.

Hash example #1

package main;

my $hash = Hash;

Hash example #2

package main;

my $hash = Hash {1..4};

number

Number(Num $data) : InstanceOf["Data::Object::Box"]

The Number function returns a Data::Object::Box which wraps a Data::Object::Number object.

Number example #1

package main;

my $number = Number;

Number example #2

package main;

my $number = Number 123;

regexp

Regexp(RegexpRef $data) : InstanceOf["Data::Object::Box"]

The Regexp function returns a Data::Object::Box which wraps a Data::Object::Regexp object.

Regexp example #1

package main;

my $regexp = Regexp;

Regexp example #2

package main;

my $regexp = Regexp qr/.*/;

scalar

Scalar(Ref $data) : InstanceOf["Data::Object::Box"]

The Scalar function returns a Data::Object::Box which wraps a Data::Object::Scalar object.

Scalar example #1

package main;

my $scalar = Scalar;

Scalar example #2

package main;

my $scalar = Scalar \*main;

string

String(Str $data) : InstanceOf["Data::Object::Box"]

The String function returns a Data::Object::Box which wraps a Data::Object::String object.

String example #1

package main;

my $string = String;

String example #2

package main;

my $string = String 'abc';

true

True() : BooleanObject

The True function returns a Data::Object::Boolean object representing a true value.

True example #1

package main;

my $true = True;

undef

Undef() : InstanceOf["Data::Object::Box"]

The Undef function returns a Data::Object::Undef object representing the undefined value.
